Fewer people were on the move in the Maldon district as they took precautions during the peak of the recent heatwave, new figures show.

The UK recorded historic temperatures on July 18 and 19, with some areas topping 40C for the first time, as the Met Office issued a red risk-to-life heat warning in some areas of the country.

An amber alert was also in place for much of England, Wales and southern Scotland.

The heatwave caused major disruption to travel and fires erupted around the country, with climate charities warning extreme temperatures will become more frequent and severe as the climate crisis worsens.

On the hottest day, people in Maldon took their own precautions, with footfall on public transport across the area down compared to the week before.

Figures from Google, which uses location data from phones and other personal devices to track trends in people's movement in different areas of their daily lives, show activity on public transport on Tuesday July 19 was 14.5 per cent below the week before.

On Monday July 18, the other day Met Office warnings were issued for, footfall was also 20.9 per cent down on the previous week.

Most places in England saw a similar pattern, with the majority of the areas bucking the trend located in Scotland and Northern Ireland.

Climate charity Friends of the Earth said many people felt "trapped in stiflingly hot homes that are poorly designed to keep out the summer heat" and warned that extreme weather is likely to become more common because of the climate crisis.

A spokesman for the UK Government said it is "taking robust action to prepare for the challenges of climate change".

"We are working to ensure our homes are fit for the future and have already committed to considering overheating and adaption when developing our future policies to future-proof our housing stock," they added.

Workplace activity around the country remained roughly the same during the hot weather, but residential footfall doubled on Monday, July 18, and more than tripled on Tuesday July 19 compared to a week earlier.

In Maldon, time spent in residential areas on Tuesday increased by 13.5 per cent.
